Primordial non-Gaussianity is a potentially powerful discriminant of the physical mechanisms that generate the cosmological fluctuations observed today. Any detection of non-Gaussianity would have profound implications for our understanding of cosmic structure formation. In this paper, we review past and current efforts in the search for primordial non-Gaussianity in the large-scale structure of the Universe.

Computing the Three-Point Correlation Function of Galaxies in $\mathcal{O}(N^2)$ Time (2015, background): “Generically, inflation must couple to ordinary matter so as to produce it during reheating, and this coupling produces some level of non-Gaussianity (Desjacques & Seljak 2010, for a recent review).”
Constraining primordial non-Gaussianity with future galaxy surveys (2011, methodology): “…deviations) are required to reproduce the N-body results when dark-matter haloes in the simulations are identified using either the friends-of-friends (FoF) or the spherical overdensity (SO) method: this makes unclear which value should be actually used for galaxies (Desjacques & Seljak 2010).”
Particle production during inflation and gravitational waves detectable by ground-based interferometers (2011, background): “1 Mpc − 1 (see [37] for a recent review), which correspond to scales that left the horizon about N C − 5 efoldings before the end of inﬂation.”
